Javascript Question

How does node js do it better?

How and when is the single threaded asynchronous processing model of nodejs a better approach than the multithreaded approach of the known server Gurus like PHP, Java and C#?. Can someone please explain to me simply and clearly?

My question is how technically is the single threaded asynchronous processing model a better approach ?

Grasping the Node JS alternative to multithreading

Node.js was created explicitly as an experiment in async processing. The theory was that doing async processing on a single thread could provide more performance and scalability under typical web loads than the typical thread-based implementation. The single threaded, async nature does make things complicated. But do you honestly think it's more complicated than threading? One race condition can ruin your entire month! Or empty out your thread pool due to some setting somewhere and watch your response time slow to a crawl! Not to mention deadlocks, priority inversions, and all the other gyrations that go with multithreading.

But is it really single threaded. Read this article https://softwareengineeringdaily.com/2015/08/02/how-does-node-js-work-asynchronously-without-multithreading/
